Comments on the geologic information

  • Geologic Description = Bundtzen and others (1991) first described Tatlawiksuk Hot Springs, a newly discovered geothermal system in western Alaska. Tatlawiksuk Hot Springs is a fairly alkaline, low-chlorine, sodium bicarbonate spring that is comparable to other Alaskan hot springs related to faulted granitic pluton-sedimentary rock contact zones. The four recognized Tatlawiksuk springs emit hot waters that reach a maximum temperature of 68 degrees Celsius; the springs plumbing system exhibits a north-south alignment parallel to high-angle faults mapped in the area (Bundtzen and others, 1991; Wilson and others, 1998). During State Land Selection resource investigations conducted by the reporter in 1992 (Division of Geological and Geophysical Surveys Staff, 1993), several grains of placer gold were detected in sinterous material at the northern end of the spring system.
  • Age = Quaternary.
